Silver is a beautiful metal; turns a really nice colour as it ages.
And, by comparison with gold, it's cheap. Throughout 2008 it averaged less that $15 per ounce. Currently it's even gone down by comparison with that (at the moment it's about $13).
Compare that with gold which is $923 an ounce today and it's easy to see why TJC are featuring silver.
Good luck to them, I say; silver is much under-rated.
